Tax Exempt Sales

Stuttering Therapy Resources is required to charge sales tax for purchases made in Michigan and Texas unless they are made by tax-exempt organizations such as schools. As a small business with nexus locations in Michigan and Texas, we do not collect sales tax in any other states. 

Online orders: If your organization is tax-exempt in Michigan or Texas, please email us at so that we can register you as tax exempt BEFORE you place an order online with a credit card. If you are ordering from any other state, the online system system will automatically remove the sales tax as soon as you enter your address.

Purchase orders: Schools, universities, and hospitals in the United States may submit POs to us via email at or via fax at 844-4-STUTTER (844-478-8883) so that we can process your order without sales tax.
